A method is provided for specifically altering the immune system response of a mammal to a specific antigen. The method comprises the steps of: (a) contacting the mammal's immune system with the specific antigen for a suitable time period so as to artificially stimulate said immune system; (b) withdrawing blood cell containing material, including antigen stimulated blood cells, from the mammal; (c) treating the withdrawn material or cells so as to alter the stimulated cells; and (d) returning the material and treated cells to the mammal. |
